CROSS-REFERENCE TO RELATED APPLICATION

This patent application is a continuation of U.S. Pat Application No. 17/808,755 filed Jun. 24, 2022, which is a continuation of U.S. Pat Application No. 17/672,778 filed Feb. 16, 2022, which is a continuation of U.S. Pat Application No. 17/466,119 filed Sep. 3, 2021 which claims priority to U.S. Provisional Application No. 63/074,144, filed Sep. 3, 2020, all of which are herein incorporated by reference in their entirety.

FIELD OF THE INVENTION

The invention relates to modular communication devices for use with mouth, nose, face, and head coverings, including masks. Modern societal health concerns often require the use of such coverings and/or masks to protect a wearer from exposure to external air, liquids, particulate, pathogenic, or other harmful substances. Although masks may protect a wearer, masks also hinder communication by reducing or muffling the wearer’s voice. The disclosure provides a modular communication device that can be attached to a disposable or reusable mask and allow a user’s voice to be amplified outside of the mask.

BACKGROUND OF THE INVENTION

The present disclosure relates to modular communication devices for use with face masks and/or coverings, with examples being N95 respirators; procedural, surgical and cloth face masks; face shields; cloth coverings such as bandanas; and continuous positive air pressure (CPAP) or other (e.g., bi-level positive airway pressure (BiPAP)) devices including masks and hoods. These modular communication devices may include a microphone, the microphone configured to interface with a wired or wireless speaker and/or a wired or wireless communications device, such as a telephone.

In almost all settings, the use of a face mask and/or covering restricts the ability to communicate naturally; coherent conversation with others or via telephone is universally difficult. This difficulty is due, at least in part, to the intervening plastic, cloth or other material, as well as to noise of the airflow and machinery and other environmental noise.

Accordingly, there is a need in the art for a modular communication device that is configured to pick up the mask wearer’s speech from within the mask or associated accessories, utilizing one or more microphones, and transmitting that speech to a speaker or other communications device to makes one’s voice heard. This communications capability/device might take the form of a coupler, a pair of magnetized devices, a clip-on or pin-on attachment, a bone conductive microphone device, a throat microphone device, or many other such exemplary implementations.

As was noted above, the present disclosure, in some embodiments, relates to a patient respiratory mask that includes a microphone disposed thereon, the microphone is configured to interface with a wired or wireless speaker and/or a wired or wireless communications device, such as a telephone. In some embodiments, the present disclosure relates to modular communication devices for use with mouth, nose, face, and head coverings, including masks. The disclosure provides for a modular communication device that can be attached to a disposable or reusable mask or face covering and allow a user’s voice to be amplified outside of the mask. While the following is described in reference to various exemplary embodiments, the present disclosure is not so limited.

In some exemplary embodiments, the microphone is a noise-cancelling microphone. In further embodiments, the microphone includes or is associated with at least one noise filter. In further exemplary embodiments, one or more of the microphone, speaker and communications device is wireless. It is to be understood that reference to a component, such as a microphone, speaker, etc., as being wireless or transmitting wirelessly encompasses configurations wherein such device is connected to a component that includes a wireless transmitter and/or receiver. Accordingly, any reference herein to a “wireless” component should be read to encompass such a construction. In further exemplary embodiments, an on-board speaker is integrated into a portion of the respiratory mask. In further exemplary embodiments, a speaker is external to the mask.

As we have noted, in exemplary embodiments, the patient respiratory mask includes an internal and/or coupler- or tube-adapted noise-cancelling microphone with wireless, e.g., Bluetooth®, capability. In exemplary embodiments, the microphone is attached to or built into a respiratory mask, a coupler designed to attach to the mask tube interface, or mask fluid delivery tube (e.g., for oxygen, air or some other gas). In additional exemplary embodiments, the coupler includes one or more of a microphone, a speaker, wiring, processor and a communications device. In exemplary embodiments one or more of the preceding elements are embedded in or provided through a portion of the coupler.

As discussed above, further exemplary embodiments, the microphone wirelessly transmits a patient’s voice, via Bluetooth® technology, to a Bluetooth® speaker in proximity to and in communication with the Bluetooth® transmitter. Reference herein to a “Bluetooth®” device refers to a device that is enabled to use Bluetooth® technology. In further exemplary embodiments, the microphone wirelessly transmits a patient’s voice, via Bluetooth® technology, to a Bluetooth® smartphone in proximity to and in communication with the Bluetooth® speaker and/or Bluetooth® transmitter. While a Bluetooth® speaker and an exemplary Bluetooth® smartphone are specifically described, the present disclosure contemplates other Bluetooth® communications devices.

Referring now to FIG. 1 , one exemplary patient respiratory mask in accordance with the present disclosure includes an exemplary microphone provided therein. In exemplary embodiments, the respiratory mask is a CPAP (or BIPAP) respiratory mask, shown generally at 10, with a mask portion 12 and a Bluetooth® microphone 14 that is incorporated within a fluid airspace, shown generally at 16, of the mask 10 near the mouth (not shown) of a patient. The exemplary mask also includes a fluid delivery tube 18 and at least one mask inlet 20.

In exemplary embodiments, the microphone 14 is mounted on or is provided within the material of the mask. In another exemplary embodiment, the microphone is provided in a separate microphone tube (not shown) that may extend at least partially into the fluid airspace of the mask 10. In further exemplary embodiments, the microphone tube is at least partially sealed, for example via plastic or a membrane that is at least moderately transparent to sound but that also separately maintains the integrity of the fluid airspace 16 within the respiratory mask 10.

Such an exemplary microphone tube may be provided within or be mounted to the respiratory mask 10, a fluid delivery tube 18, or any coupler 22 or portions intermediate the fluid delivery tube 18 the respiratory mask 10.

Referring now to FIG. 2 , another exemplary patient respiratory mask 10 incorporates such Bluetooth® microphone 14 into a coupler device 22 that is positioned between the fluid delivery tube 18 and the respiratory mask 10. In exemplary embodiments, the coupler 22 is sized and configured to provide a friction fit for the mask inlet 20 on one side and for the fluid delivery tube 18 on the other side. Referring to FIG. 3 , an exemplary coupler 22 includes a mask inlet side, shown generally at 32, a fluid supply tube side, shown generally at 34, with bulk air flow traversing the interior of the tube generally at the arrows of 36.

In an exemplary embodiment, a microphone 14 is separated from the bulk air flow 36 by a filter 38, which may be configured to filter one or more sound characteristics or to simply shield the microphone from bulk air flow. The filter 38 may be a membrane, acoustic mesh, or any other convenient sound transmitting material.

In the illustrated exemplary embodiment, the microphone is illustrated as being operatively connected to a microphone pre-amplifier 40, an equalization component 42 [for example an analog to digital converter (ADC) and digital signal processor (DSP)], a Bluetooth® transmitter 44, a sound output component, such as a digital to analog converter (DAC), amplifier (Amp) and speaker 45, an antenna 46 and a power supply 47, such as a battery or wired power adapter. These components are illustrated in this exemplary embodiment as being both connected to the microphone and as being housed on a protruding portion 48 of the coupler 22. However, it should be recognized that the microphone may be configured on-board the coupler 22 with more or fewer associated components, with some components or processes omitted or performed elsewhere, e.g., on the exterior of the coupler 22, remote from the coupler 22, etc.

Additionally, the coupler can take any convenient shape when housing such components, as long as connecting portions 32 and 34 are configured to connect to the mask inlet 20 and the fluid delivery tube 18, respectively.

In exemplary embodiments, the coupler may be configured to attach to the fluid delivery tube, regardless of any variation in tube diameter (e.g., differences in configurations warranting use of a 19 mm standard tube vs. a 15 mm thin tube). Thus, exemplary embodiments provide a universal attachment (e.g., as a clip on, etc., as shown in FIG. 4 ) configured to fit a wide array of tubes and breathing apparatuses.

In other exemplary embodiments, the microphone or other electronic components are configured to attach externally (for example as a clip-type attachment, among others) to the respiratory mask 10 but in close proximity to the patient’s fluid airspace (see 16 in FIG. 1 ). Referring now to FIG. 4A, a clip 50 is illustrated with a microphone unit 14 provided on an underside of the clip. In exemplary embodiments, the clip 50 also interfaces with a power and signal wire 54 via a port 56. While such a clip may be configured to attach anywhere that is convenient to place the microphone unit 14 near a sound transmitting surface, for example the inlet portion 20 of mask 10 or an exterior portion of a coupler 22, FIG. 4 illustrates provision of the clip 50 over a portion of the fluid deliver hose 18, with the microphone unit against or proximate the material of the hose to pick up sound vibrations transmitted through the hose. It should be recognized that while FIG. 4 illustrates a wired configuration, the microphone unit can also be configured with a battery and a wireless (e.g., Bluetooth®) transmitter. FIG. 4B illustrates an exemplary side elevation view of the clip 50, with microphone 14 positioned to be near tube 18 in an installed position.

Referring now to FIG. 5 , a fluid delivery tube 18 is illustrated as including an integrated coupler 22 that incorporates a microphone 14 (see FIG. 2 ) therein and is attachable to or integral to respiratory fluid delivery tube 18. An exemplary power cord 24 runs at least along a portion of the tube 18 to the microphone 14 (which may be configured in a wired or wireless, e.g., Bluetooth®, arrangement). As we have noted above, the coupler may also include other components, such as processing or filtering components, a wireless transmitter, etc., in addition to or alternative to the microphone, such as a speaker, wiring or any other type of communications device.

In further embodiments, the microphone 14 may be configured as a wired microphone utilizing the exemplary cord 24 or another cord for data transmission. In additional exemplary embodiments, the microphone may be wireless and may be connected to a battery source, with no cords running along a portion of the tube 18.

In further embodiments, a cord can be configured with one or more clips to secure it to the hose 18 or as an integral part of the hose 18, for example embedded or permanently attached to the tube 18 or to a tube wiring harness. Exemplary wire harness clips 62 are illustrated as attaching a cord 24 to tube 18 in FIG. 6 . In exemplary embodiments, the cord 24 is configured as a wiring harness secured at one or more places via harness clips 62, with the cord connectable to a coupler 22 (as in FIGS. 2 and 3 ) or a mask (as in FIG. 1 ). For any wired configurations, the remote (from the mask) end of the cord 24 may be configured to connect to additional components, such as a speaker, processor, network, power, etc.

The devices of the present invention can comprise several components. FIG. 11 is a block diagram illustrating the various components of an embodiment of the present invention. In this embodiment is illustrated a microphone, a microphone amplifier, a digital signal processor, a speaker amplifier, and a speaker. There is also a battery, battery management, a voltage regulator, and a USB. Other embodiments and configurations can be utilized.

FIG. 12 shows an alternative embodiment of a device of the present invention showing a flat connecting flexible cable with a mic module and a speaker module, which can be worn by a mask user as shown in FIG. 13 . The mic module portion is intended to engage with a mask clip, which can be engaged magnetically, for attachment to a mask that is interposed therebetween.

In an embodiment, the device may be a communications device dimensioned and configured to be used with a mask, or other device that is intended to cover a user’s face, nose, mouth and/or head. Commonly used face masks make communication more difficult by lowering and muffling a user’s voice. Wearing masks may reduce inherent effectiveness of the mask by requiring mask wearers to stand closer together, shout, or remove the mask to adequately communicate. The disclosed communication device when combined with a mask, allows disposable or reusable masks to improve the user’s communication from a safe distance as well as when using a phone or other communication device.

A mask may be made of cloth, paper, cardboard, plastic, or other material. The mask may be used to conceal a user’s identity, prevent the dissemination of the user’s breath or expelled gases, liquids, or particulates. The mask may also protect the user from inhaling, or receiving on the face, other gases, liquids, or other particulates. Examples of masks include those selected from the group consisting of a cloth mask, fabric mask, disposable mask, single-use mask, surgical mask, procedure mask, medical mask, plastic mask, dust mask, filter mask, respirator mask, respiratory mask, oxygen mask, KN95 mask, N95 mask, surgical N95 mask, N99 mask, KN99 mask, N100 mask, KN100 mask, R95 mask, P95 mask, P100 mask, PM2.5 mask, FFP1 mask, FFP2 mask, FFP3 mask, a CPAP mask, a BiPAP mask, multilayered mask, mask with removable filter, a face covering, handkerchief, kerchief, veil, hood, bandana, mask with fitter, mask with brace, and combinations and layered arrangements thereof.

The communication device may be removably attachable to a disposable or reusable mask, which is particularly helpful to medical professionals, patients, first responders, or anyone who desires to cover their nose and mouth and/or filter the air they breathe or expel. The communication device may be reusable so that it may be removed from a first mask to subsequent masks. In an embodiment the communication device may be modular with multiple parts allowing it to attach to a mask. The communication device may include inner and outer housings, or just one inner or one outer housing. The communication device may be autoclavable or sterilizable, or disposable.

The inner and outer housings of the communication device may each include all other necessary components for successful operation of the communication device. The housings may be constructed of any reasonable material for commercial, personal, or medical devices, such as plastics, metals, woods, or man-made or natural materials. Each housing may also include elements to secure the inner and outer housings to the mask, and to create a connection between the inner and outer housings. In order to connect the inner and outer housings to the mask, the inner and outer housings may include a mechanical clip, a spring, a magnet, pins, hook and loop, snaps, buttons, glue or other adhesives, zippers, stitches, strings, ties, staples, suction, or other connective means. Certain features (e.g. snaps, buttons, zippers) may be complementary to features on the mask. The housings may be configured to slip into and reside in a pocket or other means for securement on the mask. The inner the outer housing may be configured to attach to eyeglasses, a hat, or other wearable item which allows the inner housing to be in close proximity to the user’s mouth or nose.

The inner and outer housings may each include complementary magnetic attachments which allow the inner and outer housing to attach to one another, separated by the mask. Magnetic attachments create a secure and movable connection on the mask. The magnetic attachments may be a ring on each housing, which creates a secure connection between the inner and outer housing, and securely attaches the communication device to the mask. The complementary magnetic attachments pair to one another across the mask, yet still allow electrical signals to pass between the inner and outer housing. The complementary magnetic attachments may be a ring, or a square, or any other shape with an open center. The complementary magnetic attachments may also be a plurality of complementary magnetics on each of the inner and outer housings. The complementary magnetic attachments may have the ability to attach designs or otherwise showcase messages to the outer housing as a form of free speech or advertising.

The inner and outer elements may also be dimensioned in a curvilinear form, complementary to each other. The curvilinear form of the inner element may be placed inside the mask extending from one side to the other crossing the area in front of the user’s mouth. A speaker may be located in a central location between the sides so that it is close to the user’s mouth. Other features, such as electrical and attachment features, of the inner element may be located along the curvilinear form flanking the microphone. The curvilinear outer element may attach to the inner element by magnetic attachments at locations complementary to the inner element. In other embodiments, the elements may be part of, or attached to, an inner support frame/bracket that supports the form of the mask on the user’s face.

The inner and outer housings may contain a power source. The power source may be in both housings, or the power source may be in only one of the housings. The power source may be a replaceable or rechargeable battery. Because of the close proximity of the housings, power may flow, via induction or other modalities, from the powered housing to the non-powered housing, through the mask. Alternatively, a physical connection, as described above, may span between the inner and outer elements to provide power to the non-powered element or exchange data between the elements. In it also contemplated that the device may mate with a mask having an existing port (for airflow, etc) allowing a suitable path for a physical connection between the inner and outer elements.

One or both of the inner and outer housings may include a port and/or cable for a power source or power charging, or for data transfer. The port and/or cable may connect the housing, the element, and the device to another system for data or signal processing, charging, external speakers or communication, or any other relevant system.

The inner element may be located inside the mask in close proximity to the user’s mouth, to easily pick up the user’s voice. The inner element may act as or include a microphone and a transmitter. The inner element may transmit a signal, of the user’s voice, to the outer element. The outer element may be releasably attachable to the outside of the mask. The outer element may include a transmitter, a receiver, and a speaker, to receive the signal from the inner element and then project the user’s voice. The user’s voice may be projected via the speaker in the outer housing or the inner or outer housings may also transmit the voice signal to an external speaker or system. The speaker in the outer housing may project the user’s voice along or in combination with an external speaker or system. The microphone, speaker, and electrical processing may include any of the elements described above. The speaker may include a flared housing, such as a bull-horn to increase the user’s voice. The transmission of signal between the inner element and the outer element may be wireless or may be via a physical connection between the elements. A wireless transmission between the inner and outer elements is suitable for a reusable mask or disposable mask. The transmission of electrical signal through the physical connection may include an element, extending from the inner or outer element, that pierces through a disposable mask and makes a physical and electrical connection with the other of the inner or outer element. This connection is suitable for a disposable mask or may be used with a reusable mask.

The communication device may also include sensors for detecting ambient or expelled gas mixtures or temperature. Monitoring gases, like air quality, and temperature may be helpful in respiratory therapy of patients, for first responders, or in any scenario where a user needs a mask. The device may include a separate membrane or filter used to sample or analyze, in real time, ambient or expelled air quality for contaminants, particulates, or pathogens. The membrane may be removable, replaceable, or cleanable. Sensors in the device may include a relative or absolute humidity sensor, a temperature sensor, a dew point sensor, an enthalpy sensor, a pressure sensor, a barometric sensor, a flow rate sensor, an oxygen sensor, a carbon monoxide or dioxide sensor, a nitrogen sensor, or a combination thereof. The sensors may detect or monitor characteristics not associated with air quality, these sensors may include acoustic sensors, light sensors, cameras, ambient temperature sensors, accelerometers, or any sensor pertinent to expelled or ambient environments. It is also contemplated that a sensor may be external to the device, but connects to a port on one or both of the inner or outer housings.

In operation, the device may detect a user’s voice or sound via a microphone and reproduce that sound via a speaker. The device may include a microphone, a speaker, a processor, a battery (single use or rechargeable), a charging/data port, communications such as Bluetooth®, volume controls, lights, light-emitting displays (LEDs), a camera, a video screen, measuring ports with the ability to electronically measure breathing (and/or vapor exiting the user’s mouth), noise, speech, tones, etc. The microphone may be noise canceling. The device may provide for communication between the inner and outer elements and any external system by any wired or wireless connection, such as RFID, WiFi, Bluetooth®, Zigbee, Zwave, 2G, 3G, 4G, 5G, or any reasonable later-developed wireless modality.

The device may also include a feedback unit for the user, such as a headphone or an in-ear component. The feedback unit may assist the user in hearing the user’s voice. The feedback unit may also include an external microphone embedded in the outer element or connected to, but separate from, the outer element. The external speaker may transmit sound to the user’s ear. The feedback unit may be dimensioned and configured to include additional microphones in other locations around the user, such as at the user’s throat. The feedback unit may be useful for masks, helmets, or other item that covers or isolates the user’s head.

It is contemplated that the device may include any other reasonable technology, system, or processes to assist in communication between a user and another. These technologies include microprocessors, microcontrollers, computer chips, programmable algorithms for processing the data of the device (including sound), any component for capturing sound and human voice, speakers and any technology used to project sound and human voice, noise cancellation technology, wireless capabilities for communication between the microphone and the speaker as well as between the device and remote devices such as external speakers, portable/cellular phones, watches, computers, and televisions. The device may include voice enhancing technology and voice recognition/voice regeneration technology as well as voice command technology as found in personal digital assistants like Amazon® Alexa®.
